Hi evenger,
Since we have not heard back from you in a few days, we are closing this post for tracking purposes. However, if you are still not able to host or join a game when testing two or more instances of the same packaged game on two or more different Macs please reply and let us know if you were able to accomplish this with the Shooter Game.
*Note, I had an issue with the buttons functioning properly, but clicking anywhere on the background, then selecting the buttons allowed them to function even though they were “grayed out” initially.
